Decreasing of musculoskeletal complaints through redesigns handling arit and palu products

Abstract

Arrester and hammer products are products that are often used by construction workers and agricultural workers. Arrester products are often used as the main tool for farmers who work in the fields every day, while hammer products are the main tools of construction workers when they will connect wood to one another using nails, or a hammer is used as a tool to destroy certain objects. Tool design that does not consider work comfort, has an impact on increasing musculoskeletal complaints felt by the user. The design of this study is treatment by subject design. The sample in this study amounted to 46 workers who were included in the inclusion criteria. The results showed that there was a decrease in musculoskeletal complaints of the workers after using the results of the design of the handle of sickle and hammer products. Arit products have an impact on the reduction of users' musculoskeletal complaints by 15.517%, the results of statistical calculations show a significant difference between the use of sickle products before and after the design. The Palu product has an impact on the reduction of the user's musculoskeletal complaints by 3.681%, the results of statistical calculations show no significant difference. The mean value of musculoskeletal complaints of conventional sickle products was 189,805 ± 5,569; mean musculoskeletal complaints using Arit products designed as much as 75.870 ± 9.985; mean musculoskeletal complaints using Conventional Hammer products 89,174 ± 6,775; mean musculoskeletal complaints using Palu products were 85.891 ± 7.388. This difference is influenced by the frequency level of product use.
